2. Voluntary wheel running: patterns and physiological effects in mice
Exercise can prevent and improve the pathophysiology of diseases and promote healthy aging. Thus, understanding the mechanisms that regulate the beneficial effects of exercise may lead to the development of new strategies to enhance quality of life and to counteract chronic diseases. Voluntary wheel running is an interesting model to study the effects of exe

3. Robust pulmonary segmentation for chest radiography, combining enhancement, adaptive morphology and innovative active contours
Abstract Introduction Statistical data reveal that approximately 140 million radiological exams are performed annually in Brazil. These exams are designed to detect and to analyze fractures, caused by different types of trauma; as well as, to diagnose pathologies such as pulmonary diseases. For better visualization of those lesions or abnormalities, method

4. A New Approach for Robust Design Optimization Based on the Concepts of Fuzzy Logic and Preference Function
ABSTRACT: In this study, an efficient methodology is proposed for robust design optimization by using preference function and fuzzy logic concepts. In this method, the experience of experts is used as an important source of information during the design optimization process. The case study in this research is wing design optimization of Boeing 747. Optimizat

5. Link Optimization and Performance Analysis of a 40 Gbps DQPSK Modulated Ultra DWDM System with 32 Orthogonally Polarized channels
Abstract The demand for higher speed at a lesser transmission cost per bit resulted in growth of optical networks with improved spectral efficiency even at narrower channel spacing. Incorporation of multilevel modulation formats in DWDM system led to the exploration of the 25 GHz channel grid, popularly known as Ultra Dense Wavelength Division Multiplexed (U

6. A non-invasive plant-based probe for continuous monitoring of water stress in real time: a new tool for irrigation scheduling and deeper insight into drought and salinity stress physiology
The non-invasive, magnetic leaf patch clamp pressure probe (also termed ZIM-probe) allows for the first time to measure continuously turgor pressure changes of plant leaves over long periods of time with high precision and in real time. The probe has become an important tool in plant physiology, molecular biology and ecology, but also in agriculture because

7. Despacho online para o problema dinâmico de roteamento de veículos
The allocation of vehicles for a specific customers demand is subject to a combinatorial explosion of possibilities by the exponential increase of alternatives according to growth of the problem size. When environmental changes are considered, such as the advent of new customers, the Vehicle Routing Problem becomes dynamic and even more complex and unpredict

8. Eficiência de estimadores robustos a observações discrepantes em modelo de regressão multivariada com aplicação na análise sensorial do café / Robust estimators efficiency to outliers in multivariate regression with application in the sensory analysis of coffee
Dada a sensibilidade do método de mínimos quadrados à presença de observações discrepantes, é sabido que as estimativas de mínimos quadrados são afetadas pela presença de uma ou mais dessas observações. Frente ao exposto, esse trabalho foi realizado com o objetivo de pesquisar o efeito de observações discrepantes no ajuste de modelos de regress

9. The resigned qualification: the bad formation of workforce how a structural problem of Brazilian development / A qualificação resignada : A má formação da força de trabalho como um problema estrutural do desenvolvimento brasileiro
This work makes a diagnosis of training policy and professional education system in Brazil. The subject had never been so professional education on the agenda in the sociology of work and labor economics, but came to light at the end of the twentieth century, when the new stage of accumulation explained the decline of Fordism-Taylorism, also denouncing the n

10. Impairment of spatial performance by continuous intensive noise: a behavioral view
A wide range of animal and human investigations have tested the neurobiological and immunological aspects of noise. Few studies, however, have explored the behavioral characteristics of noise on neuromotor movements. To examine this correlation, we tested the effects of continuous intensive noise on retention and contextual transfer in a spatial memory task

11. Sobre o acoplamento fluido-casca utilizando o método dos elementos finitos / On fluid-shell coupling using the finite element method
This work consists of the development of computational tools for nonlinear geometric fluid-shell interaction analysis using the Finite Element Method (FEM). The fluid solver is explicit and its time integration based on characteristics. The computational code is able to simulate the Navier-Stokes equations for compressible flows written in the Eulerian descr

12. Fatores interferentes na indução da atividade rotacional induzida pelo teste de motricidade sobre grade em modelo animal da doença de Parkinson
Parkinson s disease (PD) is a progressive neurodegenerative disorder that affects 1% of the population above 55 years. In a previous work, it was shown that the footfault test is a tool for screening highly lesioned rats in modeling for PD using the toxin 6-hydroxydopamine (6-OHDA), which is widely used, by observing whether animals present or not context-in
